Terms of Service

A cultural reflection product

YAO is a digital cultural reflection product inspired by traditional Chinese symbolic systems, including the Four Pillars and I Ching. It is intended for personal reflection, cultural exploration, and entertainment.

The free Birth Pattern, I Ching, Library and Journal remain available without a purchase. The I Ching is a separate free tool; it is not used to generate Personal Reading.

What a reading does—and does not do

A reading offers calculated facts, authored symbolic interpretations and questions to consider. You decide how to interpret it and whether any reflection is useful in your own experience.

YAO is not a prediction of future events, a guarantee of outcomes, a personality diagnosis or a professional BaZi consultation. It does not provide medical, psychological, legal, financial, relationship or professional decision-making advice.

YAO does not guarantee wealth, health, marriage, career, luck or any other result. It does not sell practitioner consultations, paid rituals, talismans, healing claims or access to a spiritual authority.

Birth Pattern calculations and symbolic interpretations have limitations and are not scientifically established methods for predicting events or determining personality. Read Method for the current calculation boundary.

Personal Reading

The launch price is US$19 for a one-time digital Personal Reading. There is no subscription or recurring renewal. Checkout is temporarily unavailable while payment integration is being finalized.

The product is one personalised, English-language digital reading with eight chapters, generated by YAO from the birth information you supply. Calculated facts are separated from traditional symbolic interpretation and general practices. It includes no practitioner consultation.

The product page, Delivery Policy and Refund Policy explain what you receive, fulfilment and refund handling when checkout is enabled.

Your information and eligibility

Enter your birth information as accurately as you can, including the selected time zone. If your birth time is unknown, the report uses reduced scope and identifies what is missing. YAO does not invent a birth time.

To make an online purchase, you must meet the legal age requirement where you live or have permission from your legal guardian.

Our Privacy Policy distinguishes the free tools from paid fulfilment.

Personal use and intellectual property

You may save and read your report for your own use. YAO’s brand, design, authored text system and software may not be copied in bulk, resold or repackaged without permission. The rights and licences of acknowledged open-source contributors remain their own.
